HaMaariv Aravim, or simply Maariv Aravim, is the first blessing before the Shema and generally the opening prayer during Maariv. It is considered to be the parallel prayer to Yotzer ohr, which is recited in the same place at Shacharit.[1] Just as Yotzer Ohr speaks of the coming of light, HaMaariv Aravim speaks of the coming of darkness.[2]
HaMaariv Aravim and Ahavat Olam being recited at the beginning of Maariv is seen as a preparation for the recitation of the Shema in the form of an affirmation of unity.[3]
